If a man don't go his own way, he is nothing.

Nobody ever lies about being lonely.

James Dean's death had a profound effect on me. The instant I heard about it, I vomited. I don't know why.

I keep my family out of my public life because it can be an awful nuisance to them. What's my mother going to tell strangers anyway? That I was a cute baby and that she's terribly proud of me? Nuts. Who cares?

The only line that's wrong in Shakespeare is 'holding a mirror up to nature.' You hold a magnifying glass up to nature. As an actor you just enlarge it enough so that your audience can identify with the situation. If it were a mirror, we would have no art.

A man should be what he can do.

Noah, from 'The Young Lions' (1958), was the best performance of my life. I couldn't have given more of myself. I'll never be able to do it again. Never.
